Steam Trap
Type 13 E
Fig. 1 ⋅ Type 13 E Steam Trap
1. Design and principle of operation
The steam trap basically consists of the controller housing including seat and the operating element with firmly connected plug.
The operating element consists of a metal bellows filled with a water-alcohol mixture.
The device operates according to the tension
Edition March 1994
principle (liquid evaporation). Any change of
temperature of the discharging condensate
causes travel changes of the operating element and also the connected plug. Restriction or enlargement of the free area between
the seat and plug is also a result.

The steam pressure curve of the liquid steam
mixture in the metal bellows largely corresponds to that of the water. An increased temperature of the water-alcohol mixture causes,
for example, increased pressure in the operating element (2) and also result in closing of
seat (4) and plug (3). In this closing state, the
accumulated condensate cools down, as well
as the water-alcohol mixture. The pressure in
the operating element decreases, and the
valve opens; the condensate and any air
which exists is discharged.

4. Dimensions in mm and weights
2.1 Strainer
In order or ensure proper operation of the
controller, it is recommended to install a
SAMSON Strainer Type 1 directly preceding
the device.
3. Maintenance
First relieve all pressure from the plant and
drain it before disassembling the controller
and exchanging a defective operating element (2). Unscrew the cover (1) only in a
cooled-down condition, replace the seal
(2.1) on the operating element.

S/C
The steam trap may only be installed in horizontally running pipelines. The direction of
flow must agree with the arrow on the housing.
The instrument can be used as a globe or
angle valve if the screw plug (5) is screwed
accordingly.
The steam trap must be installed directly behind the outlet of the unit. For those units in
which the heating register is to be kept free of
condensate, install it approximately 1 m from
the outlet connection in the non-insulated pipeline. The condensate pipe behind the outlet
should be installed with a slight gradient.
